Tomb Raider Underworld Walkthrough & Strategy Guide

Take out the hammer while underwater -- it is faster than the speargun against the sharks but does a lot more damage. There are some pieces of a puzzle to solve in order for Lara to enter the ancient citadel.

Go under water and locate the large statues on both sides of the bridge. To unlock the drawbridge, Lara needs to go in to the helmets of the statues and turn their cranks to raise their swords.

One of the statues requires some repair. Look for the two gears near the busted statue and place them back into the statue and work the switch. The next step is to get the four power sources so the drawbridge's switch can operate.

The power sources are scattered in the two towers to the left and right of the drawbridge. The first and second power sources may be found inside the left tower (if Lara faces the ruins). Enter the tower, swim through the wreck and snag the two power sources -- one is underwater and the other out of the water.

The third power source is next to the power receptacles for the drawbridge switch. Take it as you go to the next (right) tower. The fourth power source is in the right tower and easily fetched after a short climb.

Tunnel to Helheim

The submarine tunnel to Helheim is only treasure riddled, but no enemies. Note you should try and get all the treasures now while Lara still has a SCUBA. After this section, she will lose her SCUBA and will not be able to exit from the city (not enough oxygen).

The hammer makes the poison lake easy to get across. Just use it to blast everyone you don't like and hop across the pool to the gate Natla opened. If you are after the relic though, you will be in for a tougher time.

Arctic Sea Relic

This relic is tedious to unlock, since one mistake means you need to get back to a certain spot. The timer may start with the last switch, but if you let Lara linger around too long, all the switches to access the way to the relic will reset.

In the room past the zombie infested hallway, there is a lot of broken ground and poison water all around. You need to activate four rune switches and -- before time runs out -- use the anchor ring to get to the relic before the timer runs out. If time runs out, the poison cascade flows again, killing Lara instantly.

The first switch is on the side of Helheim where Lara first sees Natla performing her ritual. it is on the entrance door's right side.

The second switch is across the first balance beam, before Lara reaches the platform with the anchor ring.

The third switch is at poison water level, past the platform with the anchor ring.

The fourth switch is on the side of Helheim, next to the room's exit to Jormungandr.

After all four switches are pressed, Lara has about 1 minute to get back to the platform with the anchor ring, hook on, and swing (don't forget to adjust the length of the wire) to the relic's resting place. Save afterwards, and should you die, you will start back at the checkpoint with the relic saved.
